Why do people cheat?

Short Answer

People cheat for various reasons including relationship dissatisfaction, opportunity, desire for novelty, low commitment, personal values, and sometimes as a response to unmet emotional or physical needs.

Detailed Explanation

Background

Cheating in relationships is a complex and painful topic that affects many people. While cheating is often viewed as a simple moral failing, research shows that the reasons people cheat are multifaceted and involve psychological, emotional, and situational factors. Understanding why people cheat doesn't excuse the behavior, but it can help those affected make sense of what happened and make informed decisions about their relationships. Understanding Why do relationships fail? reveals how relationship problems can contribute to cheating.

Research in relationship psychology shows that cheating often stems from unmet needs, relationship problems, or personal issues rather than simply being a character flaw. By understanding the underlying reasons, people can address relationship issues proactively, make better choices, and heal from the pain of infidelity. This understanding also helps prevent future cheating by addressing root causes. Cheating involves dishonesty, as explained in Why do people lie?, and rebuilding trust after cheating requires learning How to build trust?.

Scientific Explanation

People cheat for several interconnected reasons:

  1. Relationship dissatisfaction: Unhappiness in the current relationship, whether emotional, physical, or both, can lead people to seek fulfillment elsewhere.

  2. Opportunity and circumstances: Sometimes cheating happens when opportunity presents itself, especially when people are away from their partner or in situations that make cheating easier.

  3. Desire for novelty: Some people seek excitement, variety, or validation through new relationships or experiences.

  4. Low commitment: People who aren't fully committed to their relationship may be more likely to cheat.

  5. Unmet needs: When emotional, physical, or psychological needs aren't met in a relationship, some people seek to fulfill them elsewhere.

  6. Personal values and history: Individual values, past experiences, and personal history can influence the likelihood of cheating.

Real Examples

  • Someone cheats because they feel emotionally disconnected from their partner and seek emotional intimacy elsewhere.

  • A person cheats during a period of relationship conflict, seeking comfort or validation from someone else.

  • Someone cheats when traveling for work, when opportunity and distance from their partner make it easier.

  • A person cheats because they feel their needs aren't being met and don't know how to communicate or address them in their relationship.

  • Someone cheats as a way to end a relationship they're unhappy in but don't know how to leave directly.

Practical Application

How to Apply

To address or prevent cheating:

  1. Communicate openly: Regularly discuss your needs, feelings, and concerns with your partner to address issues before they lead to cheating.

  2. Address relationship problems: Work on relationship issues proactively rather than avoiding them, which can lead to dissatisfaction and cheating.

  3. Set clear boundaries: Discuss and agree on what constitutes cheating in your relationship to avoid misunderstandings.

  4. Seek help when needed: If you're considering cheating or struggling with relationship issues, seek couples therapy or individual counseling.

  5. Understand your needs: Reflect on what needs might be unmet and find healthy ways to address them within your relationship.

  6. Make conscious choices: If you're tempted to cheat, pause and consider the consequences and whether there are better ways to address your needs.
